Thanks to Luiz Amaral for the idea.

2022-05-15BGP: Improve tx performance during feed/flushOndrej Zajicek
The prefix hash table in BGP used the same hash function as the rtable. When a batch of routes are exported during feed/flush to the BGP, they all have similar hash values, so they are all crowded in a few slots in the BGP prefix table (which is much smaller - around the size of the batch - and uses higher bits from hash values), making it much slower due to excessive collisions. Use a different hash function to avoid this. Also, increase the batch size to fill 4k BGP packets and increase minimum BGP bucket and prefix hash sizes to avoid back and forth resizing during flushes. This leads to order of magnitude faster flushes (on my test data).

2022-05-04Unified attribute and filter typesMaria Matejka
This commit removes the EAF_TYPE_* namespace completely and also for route attributes, filter-based types T_* are used. This simplifies fetching and setting route attributes from filters. Also, there is now union bval which serves as an universal value holder instead of private unions held separately by eattr and filter code.

2022-04-22Babel: Fix compilation when LOCAL_DEBUG is set in packets.cToke Høiland-Jørgensen
The debug output was not updated with the rest of the code, so packets.c fails to compile if LOCAL_DEBUG is set.
2022-04-22Babel: Send out low-interval hello on shutdownToke Høiland-Jørgensen
When shutting down a Babel instance we send a wildcard retraction to make sure all peers can quickly switch to other route origins. Add another small optimisation borrowed from babeld: sending a Hello message (along with the retraction) with a very low interval. This will cause neighbours to modify their expiry timers for the node's state to quickly time it out, thus conserving resources in the network.
2022-04-13RIP: fixed the EA_RIP_FROM attributeMaria Matejka
The interface pointer was improperly converted to u32 and back. Fixing this by explicitly allocating an adata structure for it. It's not so memory efficient, we'll optimize this later.
2022-04-07BFD: Add 'strict bind' optionOndrej Zajicek (work)
Add BFD protocol option 'strict bind' to use separate listening socket for each BFD interface bound to its address instead of using shared listening sockets.
2022-04-06BGP uses lp_save / lp_restore instead of linpool flushingMaria Matejka
It is too cryptic to flush tmp_linpool in these cases and we don't want anybody in the future to break this code by adding an allocation somewhere which should persist over that flush. Saving and restoring linpool state is safer.

2022-02-27Babel: Fix bug in iface reconfigurationOndrej Zajicek (work)
A recent change in Babel causes ifaces to disappear after reconfiguration. The patch fixes that. Thanks to Johannes Kimmel for an insightful bugreport.

2022-02-06BGP: Implement flowspec validation procedureOndrej Zajicek (work)
Implement flowspec validation procedure as described in RFC 8955 sec. 6 and RFC 9117. The Validation procedure enforces that only routers in the forwarding path for a network can originate flowspec rules for that network. The patch adds new mechanism for tracking inter-table dependencies, which is necessary as the flowspec validation depends on IP routes, and flowspec rules must be revalidated when best IP routes change. The validation procedure is disabled by default and requires that relevant IP table uses trie, as it uses interval queries for subnets.
2022-02-06Nest: Attach prefix trie to rtable for faster LPM and interval queriesOndrej Zajicek (work)
Attach a prefix trie to IP/VPN/ROA tables. Use it for net_route() and net_roa_check(). This leads to 3-5x speedups for IPv4 and 5-10x speedup for IPv6 of these calls. TODO: - Rebuild the trie during rt_prune_table() - Better way to avoid trie_add_prefix() in net_get() for existing tables - Make it configurable (?)
